Using SystemCHANGE™ to Enhance Medication Adherence in Older Adult Stroke Survivors

实验性的：SystemCHANGE™

行为的：SystemCHANGE™

During the intervention phase, the PI will visit both groups of participants at home at baseline and telephone them three times (day 3 ±2 days and months 1 and 2). Refer to tables 1 and 2 for intervention details. Treatment participants will implement SystemCHANGE™ activities related to medication taking with the assistance of the PI while attention-control participants will receive patient education materials on stroke. Perceived health data will be collected during the intervention phase. A 1-month maintenance phase follows the intervention phase. Electronic medication monitoring continues, but no intervention is delivered to either group.

有源比较器：Attention-Control

行为的：Attention-Control

An experienced stroke nurse will deliver the attention control intervention. Table 3.2 shows the 2-month attention-control intervention. The stroke materials were developed by the Saint Luke's Marion Bloch Neuroscience Institute and are given to every stroke patient prior to dismissal. The PI will call participants at day 3 ±2 days, and months 1 and 2 to review chapter(s) from the book and answer questions about it. Interval, frequency, and setting are all exactly the same for the intervention and control groups. If the control participant raises questions about medications or medication-taking, PI will refer them to their Neurologist.

Acceptability and feasibility

Open ended questionnaire

Social Support

The Social Support Appraisals Index (SS-A) is a 23-item self-administered, a self-report scale measuring the degree to which a person feels cared for, respected, and involved with family and friends. The scale had good reliability and validity (Cronbach α coefficients .90, .81, and .84) (Vaux et al., 1986).

Perceived Health

Perceived health status will be measured by one question, "How is your health in general?" Participant select excellent, very good, good, fair, poor, or very poor. Perceived health status reflects people's overall perception of their health, including both physical and psychological dimensions.

Personal Systems Behaviors

The Systems Thinking Survey (adapted for patients), a 20-item, 5-point Likert response scale measuring perceptions of personal system behaviors.

Medication Adherence

MA data will be retrieved from the MEMS®cap which is a medication cap containing a battery and microelectronics that records the date and the time of each cap removal to create a medication "event" ("MEMS® Cap versatile adherence monitoring cap," n.d.).
